Comparison of I-gel and SaCoVLM in Laparoscopic Cholecystectomy
Comparison of Airway Performance Between I-gel and SaCoVLM in Patients Undergoing Elective Laparoscopic Cholecystectomy: A Prospective Observational Study
연구 개요
상태
상세 설명
Laparoscopic surgery requires the creation of pneumoperitoneum and frequently involves patient positioning changes, both of which can increase intrathoracic and airway pressures. These physiological changes may affect the performance of supraglottic airway devices and challenge effective ventilation.
Second-generation supraglottic airway devices are increasingly used as alternatives to endotracheal intubation in laparoscopic procedures because they provide effective ventilation while reducing airway-related complications. The i-gel is widely used due to its ease of insertion, integrated gastric drainage channel, and favorable safety profile. The SaCoVLM (Video Laryngeal Mask) is a novel supraglottic airway device that enables direct visualization of laryngeal structures during placement, allowing confirmation of optimal positioning and potentially improving airway management.
This prospective observational study will compare the i-gel and SaCoVLM in adult patients undergoing elective laparoscopic cholecystectomy under general anesthesia. Ventilation performance, airway sealing pressure, insertion success, ease of placement, hemodynamic responses, and perioperative airway-related complications will be assessed. The findings may provide further evidence regarding the clinical performance and safety of these devices during laparoscopic surgery.
